使用Gnuplot splot与haskell元组列表？ [英] Using Gnuplot splot with haskell list of tuples?

问题描述

所以我在haskell中有gnu，并且想要绘制3d曲面。从我的理解，似乎我将不得不建立一个文本文件名data.txt，它有这个

so i have gnu in haskell and want to graph 3d surfaces. From my understanding it seems like i would have to make a text file name data.txt and it having this

1 1 4
1 2 3
1 3 1
1 4 5
2 1 1
2 2 4
2 3 6
2 4 1
3 1 0
3 2 2
3 3 7
3 4 1
4 1 1
4 2 5
4 3 4
4 4 7

然后用线条对数据进行处理。不过，我在haskell中有一个列表，其中包含代表这些点中的每一个的元组。有谁知道我可以如何使我的列表工作，而不是将我的数据以某种方式放入文本文件？

Then doing splot "data" with lines. however, i have a list in haskell, that contains tuples that represent each of these points. Does anyone know how i can make this work with my list rather than putting my data in a text file somehow?

推荐答案

您可以在 documentation ：

You can see the example given in the documentation:

λ> import Graphics.Gnuplot.Simple
λ> let xs = [-2,-1.8..2::Double] in plotMesh3d [] [] (do x <- xs; return (do y <- xs; return (x,y,cos(x*x+y*y))))

产生这样的结果：
